I have several of this lens, and it is SUPERB. It's considered one of Tamron's finest lenses ever. Sharpness rivals primes throughout the range, and I use it as a benchmark against other lenses when testing at 80-200 range. It will equal or beat the SIgma 70-210/2.8 I believe...which is one of the best AF lenses in this range. Robert James - This message is from the Pentax-Discuss Mail List.
